Groat's concerns came on the same day Tigers coach Tim Sheens said his young prop had been restricted to light duties, and the Broncos revealed Te'o would be represented by Peter Shields - the same Brisbane lawyer who helped Queensland great Alfie Langer fight a drink-driving charge in 2010.

"He shouldn't get off, and if he does it will only open the door up for others," Peter Groat said.

"I don't think the shoulder charge should be removed from the game. I also don't think there was any intent, but you have to stop attacking the head.

"If you do take the chance and hit a player's head, you have to pay the penalty."

"It's a shame because Matt was only on for two minutes and they couldn't use an 18th man (as a replacement) because of dirty play."
